Weather in December
Temperature
Barreirinhas experiences an average high-temperature of a still tropical 30.9°C (87.6°F) in December, marking an insignificant shift from 31.5°C (88.7°F) in November. Barreirinhas indicates a consistently low-temperature of 26.1°C (79°F) during the nights of December.Heat index
December's heat index is appraised at a fiery hot 39°C (102.2°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.Heat index determinations are made taking into account the shade and light air movements. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
